    ...ehh

    The coating on the metal base was atrocious and scratches off easily. The shelf for the battery pack was also folded over too far and I had to literally sand the battery down to get it in. There wasn't enough space for the power cord and it has to be jammed in at an awkward angle. Overall, mediocre design and pretty poor fabrication AndyMark Response: We designed the sheet metal housing to fit the battery under the flap while using flat head screws to attach the ball caster. Please make sure you are using flat head screws instead of the pan head screws in this area. The aluminum should have been type II hard black anodization.
